The Young Mother and the Labor Market

Introduction - The Centro de Orientacao ao Adolescente of Campinas (Southeastern Brazil) maintains a program to qualify economically disadvantaged adolescent students aged 15 to 18 years to enter the labor market. Objective - To understand life projects of teenagers who became mothers while participating in the program, in the period from 2003 to 2008, aiming to find the place of professional life in their life trajectory before and after motherhood. Method - Eight young mothers were interviewed, and a qualitative methodology was applied to the analysis of the interviews. Results - The trajectories of study and work were discontinued or adapted due to motherhood. Four young mothers completed high school and none had entered university. Three did not return to work and the rest had diverse work experiences. The reported difficulties to enter the labor market were: inadequate instruments to support the children's care, low income, lack of work experience, presence of small children and little educational background. Final Considerations - Teenage motherhood did not indicate the exclusion of educational or work projects but indicated adjustments and the need for a family and social support network. It was noted the need for public policies targeted at the inclusion of youths in the labor market and at support services such as nurseries. Also, the need for a change in gender relations was demonstrated, with greater equality of rights as a precondition for the inclusion of women, especially those who are mothers, in the labor market.

Employment Effects of Product and Labour Market Reforms: Are There Synergies?

This article investigates the effect of product market liberalisation on employment allowing for interactions between policies and institutions in product and labour markets. Using panel data for OECD countries over the period 19802002, we present evidence that product market deregulation is more effective at the margin when labour market regulation is high. The data also suggest that product market liberalisation may promote employment-enhancing labour market reforms.

Batrachochytrium dendrobatidis in amphibians confiscated from illegal wildlife trade and used in an ex situ breeding program in Brazil

This paper describes an outbreak of chytridiomycosis affecting a group of Dendrobates tinctorius, a Neotropical anuran species, confiscated from the illegal wildlife trade and housed in a private zoo in Brazil as part of an ex situ breeding program. We examined histological sections of the skin of 30 D. tinctorius and 20 Adelphobates galactonotus individuals. Twenty D. tinctorius (66.7%) and none of the A. galactonotus were positive for Batrachochytrium dendrobatidis (Bd). Multiple development stages of Bd infection were observed. The reasons for the interspecific difference in the rate of infection could not be determined, and further studies are advised. Because the examined population consisted of confiscated frogs, detailed epidemiological aspects could not be investigated, and the source of the fungus remains uncertain. The existence of ex situ amphibian populations is important for protecting species at higher risk in the wild, and ex situ amphibian conservation and breeding programs in Brazil may be established using confiscated frogs as founders. However, this paper alerts these programs to the urgency of strict quarantine procedures to prevent the introduction of potential pathogens, particularly Bd, into ex situ conservation programs.

Human respiratory syncytial virus N, P and M protein interactions in HEK-293T cells

Characterization of Human Respiratory Syncytial Virus (HRSV) protein interactions with host cell components is crucial to devise antiviral strategies. Viral nucleoprotein, phosphoprotein and matrix protein genes were optimized for human codon usage and cloned into expression vectors. HEK-293T cells were transfected with these vectors, viral proteins were immunoprecipitated, and co-immunoprecipitated cellular proteins were identified through mass spectrometry. Cell proteins identified with higher confidence scores were probed in the immunoprecipitation using specific antibodies. The results indicate that nucleoprotein interacts with arginine methyl-transferase, methylosome protein and Hsp70. Phosphoprotein interacts with Hsp70 and tropomysin, and matrix with tropomysin and nucleophosmin. Additionally, we performed immunoprecipitation of these cellular proteins in cells infected with HRSV, followed by detection of co-immunoprecipitated viral proteins. The results indicate that these interactions also occur in the context of viral infection, and their potential contribution for a HRSV replication model is discussed.

Dendritic cells and T lymphocytes interactions in a novel 3D system

We describe the interactions between monocyte-derived DCs, in different stages of maturation, with allogeneic T lymphocytes in a 3D system. Maturation of DCs increased their interaction time with T lymphocytes from 43 to 138 minutes. The average motility of T lymphocytes interacting or not with DCs was also affected, varying from 0.21μm-0.37μm/minute to 0.36μm- 0.52μm/minute. These data indicate that this 3D BiotekTM scaffold enables interactions between lymphocytes and DCs at different stages of maturation and may be useful for the characterization of these interactions, the cellular subtypes and patterns of response induced.
